Sow tomato seeds in flats 6 to 8 weeks prior to transplanting outdoors. Tomato seeds will not germinate in cool soil. Be sure soil temperature is at least 75 degrees F. Plant seed 1/4 in. deep.
When plants are 1-1/2 in. high, transplant into Jiffy pots. Transplant outdoors 3 to 4 ft. apart only when night time temperature stays above 45 degrees F. Maturity dates are from date of outdoor transplanting. One ounce produces 1,000 plants.
